Step 4: Connect air tube to the pump- and control unit
Both ends of the air tube need to be connected to one T-junction. Integrate the back pressure valve with two
short air tubes and connect the remaining end to the air outlet nozzle of the pump- and control unit (refer to
Figure 13 and Figure 14).
Note:
The installed air tubing shall realize a closed loop. Avoid open or dead ends.
Note:
For 48V battery systems with larger cells (18 OPzS solar.power 3250 up to 26 OPzS solar.power 4700)
two electrolyte circulation pumps are required. In that case two separate air tube loops need to be realized.
Arrange the tubing in a way that each pump is connected with each cell of the battery system. One pump
serves as a master and is connected to the current sensor. The master pump activates / deactivates the
slave pump via a control wire (refer to Figure 5).
